Abstract

The development of microstructure, texture, misorientation and grain boundary character during
cyclic deformation of Nickel at elevated temperatures was investigated. At high numbers of cycles
grain boundaries align with the maximum shear stress. Texture and microstructure change significantly
and low ∑CSL boundaries with (111) rotation axes emerge. The Schmid factor increases with
progressing deformation but Sachs- and Taylor-type deformation modelling fail to predict the actual
texture change. It is proposed to attribute the observed texture and microstructure development to an
interaction of deformation mechanisms with grain boundary motion.
